Wow, that's very interesting. It's not for me though, haha. To submerge myself in cold water (even though that's quite common here).
That was also a nice reminder, I studied one semester at Charles University in Prague, long time ago, haha. Had the time of my life.
Then there's a whole passage about a study made on hibernating squirrels, but I spare you that part haha.
Haha. Please don't hold back. Always happy to hear your thoughts.
